This invention relates to switch-stands for operating railway track switches and has for Y,

eral bolts and nuts which required considerable time to assemble and were even more troublesome to remove when repairing the stand due to their becoming rusted.

The present invention provides a novel link connection between the operating lever and locking sleeve which is free of bolts or pins and, therefore, is readily assembled and dissembled.

In the drawings:

Figure 1 is an elevation of a switch-stand constructed in accordance with this invention.

Figure 2 is a fragmentary side elevation of the upper portion of the stand.

Figure 3 is a vert-ical sectional elevation through the stand.

Figure 4 is a sectional plan taken on the line IV-IV of'Figure 3.

Figure 5 is a sectional plan taken on the line V-V of Figure A3.

Referring more particularly to the drawings the letter A Vdesignates'the stand as a whole which comprises a base 2, a safety sleeve 3 being mounted in said base and yield'- ably held against rotation by spring pressed rollers 4. A switch operating shaft 5 is journaled vertically in said base and has its lower end connected to a switch throwing lever 'i v 6, while its upper end projects materially above said base and carries an indicating sig nal 7at its upper end.

A. squared sleeve Sis mountedaround the squared upper end of the shaft 5 and has its lower end in engagement with the safety v sleeve 3, while its upper end is locked to the shaft 5 by a pin or bolt 9 thus preventing Vend of the sleeve .12 by a bolt or. pin 18 for vertical movement of the shaft 5 and sleeves 3 Vand 8 while'permittingrotary movement of the shaft 5 and sleeveS relative to 'said base.` ,A locking sleeve12 is mounted around the sleeve V8 and has its lower end squaredyas at y 13, to lit around said sleeve 8 and preventro tation of said sleeves relative to each other. rl`he sleeve 12 is free to slide vertically relative to the sleeve 8.

Vrfhe lower end of the sleeve` 12 is reduced 55 gages theupperend of the sleeve 3. Vl/Vhen the' portion 14 of the sleeve 12 is engaged in the grooves 16 vthe .sleeve 12,' sleeve 8 and shaft are all held against rotation.

'An operating lever 16a having/a forkedyattaching end 17 is -pivotally connected tothe sleeve Sfat a pointmateriallyabove the upper vertical Vswinging movement; The forked ends 17 Yof said lever are provided with hollow cylindrical enlargements 19 adjacent Y i their ends which .open inwardly. Y Y The sleeve 12 isalso providedzwith lhollow cylindrical enlargements 2O at diametrically opposite points adjacent itsupper end. fA pair .of connecting'links 21 .having ycylindrical-projections 22 adjacent* each .end are f mountedwith theirprojections in saidlhollow recesses so as toform pivoted link connections between the lever 16a and the sleeve 12. rllhe lever 16.a iS provided with any elongated slot 24 intermediate its ends which is adapted' to fit overarigid apertured lug. 25 on the sleeve/12 and to be locked against vertical swinging movement byfa pad-lock 2.6 secured inthe apertureof the lug- 25.

In operatiomwhen it is desired to operate the 'switch the pad-lock 26 will be removed andthe lever 16? swung upwardlythus caus-l 9U l ing the links 21 to pull the sleeve 12 upwardly, releasing said sleeve 12 from the sleeve 3 and permitting the rotation of the shaft 5 toy operate the switch. Y

The links 2l are of novel construction and are pivotally mounted by means of the integral projections22, thus eliminating the use of bolts or pins for this purpose.

It will be understood that while this invention has beenV shown in connection with a high7 type switch-stand it is not limited thereto but may be applied to either the high or low type stands. l Y Y lhile I have shown and described a certain specific embodiment of my invention it will be understoodthat I do not wish to be enlargements adjacent their ends and opening inwardly, said sleeve being also provided with hollow` cylindrical enlargements at diametrically opposite points adjacent its upper.
